Riassunto
In Italia, l’elevata prevalenza delle gammopatie monoclonali nella popolazione adulta e l’alta cadenza con la quale si richiede l’elettroforesi delle proteine sieriche, per svariate esigenze cliniche, determinano due conseguenze. Da una parte è relativamente frequente il riscontro occasionale nella storia di un individuo di una componente monoclonale (CM) sierica, dall’altra si rende necessario inquadrare correttamente i dati laboratoristici e programmare successivamente esami diagnostici mirati e appropriati. Il gran numero di lavori scientifici pubblicato a livello internazionale negli ultimi 15 anni, soprattutto da ematologi clinici, ha attribuito un’importanza determinante ai test di laboratorio nella gestione dei pazienti con gammopatie monoclonali, ma non sempre ha dato indicazioni univoche e coerenti sulla scelta dei test di laboratorio da praticare nelle diverse situazioni cliniche e sulle modalità di esecuzione e d’interpretazione degli stessi. A questo proposito, il Gruppo di Studio “Proteine” della Società Italiana di Patologia Clinica e Medicina di Laboratorio (SIPMeL) ha considerato opportuno raccogliere in un documento una serie di “raccomandazioni” sull’utilizzo dei test di laboratorio, in particolare di quelli compresi nella disciplina Protidologia, nella diagnosi, prognosi e follow-up delle gammopatie monoclonali. In appendice vengono riportate note metodologiche riguardanti aspetti pre-analitici e analitici controversi, relativi all’esecuzione dei principali esami di laboratorio descritti nel testo.
Summary
In Italy, the high occurrence of monoclonal gammopathies in adults and the high frequency of requests for serum protein electrophoresis have two consequences. On one hand it is relatively frequent in a person’s history to come across a serum monoclonal component; on the other it is necessary to correctly frame the laboratory data and, consequently, plan the appropriate targeted lab tests. In the last fifteen years, the international scientific publications (mainly by clinical hematologists) have shown the great importance of lab testing in the management of patients with monoclonal gammopathies. However these studies have not always given coherent and precise indications on the appropriate choice of laboratory tests in different clinical situations, or how to correctly perform and interpret them. In this regard, the Study Group “Proteins” of the Italian Society of Clinical Pathology and Laboratory Medicine (SIPMeL) has collected in a document a series of “advices” on the use of laboratory tests in the diagnosis, prognosis and follow-up of monoclonal gammopathies, in particular those included in the branch that studies the plasma protein assays. The appendix shows methodological notes concerning controversial analytical and pre-analytical aspects of the execution of the main laboratory tests described in the paper.
